Title: Improvements in the coating with luminescent material of the inner surface of a hollow vessel
IPC: H01J9/22
Filed: 1939-01-31
Abstract: 524,507. Coating by spraying. GENERAL ELECTRIC CO., Ltd. (Patent-Treuhand-Ges. fur Elektrische Gluhlampen.). Jan. 31; 1939, No. 3252. [Class 95] In a process of coating the inner surface of a hollow vessel with luminescent material, a machine is used comprising (1) a jet and means for directing from it, against the surface, a stream of gas in which are suspended finely divided luminescent material and binder in the form of finely divided spray, and (2) mechanism for producing automatically a motion of the jet relative to the surface so that the stream travels over the whole surface to be coated. The machine may comprise also (3) regulating means for controlling the rate of flow of luminescent material and/or binder from the jet, so that the amount ejected when the jet is pointing in any direction is related to the area to be coated in that direction, so that a uniform coating of luminescent material is obtained. In the machine illustrated, the bulb 20, to be coated internally with luminescent material, is carried and rotated by a sleeve 4, slidable within a driven wheel 3. The sliding of the sleeve 4 is controlled by a fork 12, 13 and a cam 18. The jet consists of orifices in the surface of a drum 24. Binder, from the tube 26, is red to the tube 47, and air, entering at 27, is fed to the tube 55, so that the binder issues as a spray. The flow of binder is controlled by a needle valve 28 and cam 31. Air carrying the luminescent material issues from larger orifices 58. Rotation of the drum 24 is controlled by a string 37, 38 and a cam 44. Excess of coating material is carried away by a pump connected with the tube 59. In use, the bulb is constantly rotating, and the jet is first directed to the bottom of the bulb. The jet is then raised, by rotating the drum 24, quickly at first, more slowly as it approaches the Equatorial plane of the bulb, and more quickly again as it approaches the neck. The bulb is then lowered to bring the jet within the neck, and the binder supply is cut down. Finally the supply of both binder and luminescent material is cut off.

[Class 7 (v)] In an electric starter provided with a hollow armature shaft 3 through which extends the spindle 20 carrying the starter pinion 26, the spindle 20 is connected to, and disconnected from the shaft 3 by a sleeve 12 slidable on the spindle 20 and having clutch. teeth 15 engageable with teeth 5 on a clutch member 4 splined on the shaft 3. The sleeve 12 is connected by a frictiondisc coupling 14 to a member 16 splined on the spindle 20 and retained by a nut 17. The friction coupling and clutch members &c. are protected by a sleeve 8. A threaded portion 11 of the sleeve 12 engages a screw thread 10 in the hollow shaft 3, the sleeve 12 and member 16 being normally held in the position shown by a spring 40. The starter pinion 26 is secured by a bolt 23 to the end 22 of the spindle 20. When the motor is switched on, the threaded connection 10, 11 advances the spindle 20 and pinion 26 until an enlargement 21 on the spindle engages a bearing 30, and further advancement of the sleeve 12 then compresses the spring 40 and brings the clutch 15, 5 into engagement for driving the spindle 20 and pinion 26. If the teeth of the pinion clash with those of the engine member 28, the continued advance of the sleeve 12 compresses the spring 40 and increases the friction in the threaded connection until the spindle 20 turns sufficiently to bring the teeth into register. When the engine starts, the pinion is withdrawn by the action of the threaded connection 10, 11 and the rearward movement is limited by the engagement of projections 9, 19 on the sleeve 8 and the friction coupling 14.

Abstract: 478,777. Fluid-pressure servomotorcontrol systems. ASKANIA - WERKE AKT.-GES. VORM. CENTRALWERKSTATT DESSAU UND C. BAMBERG-FRIEDENAU. Feb. 8, 1937, No. 3764. Convention date, Feb. 6, 1936. [Class 135] Automatic control for steering apparatus especially for aircraft, having a motor for operating a control surface, such as a rudder, and a relay for controlling the motor, has means provided for varying the immediate response of the relay to its controlling influence in dependence on the speed in such manner that it decreases with increasing speed and vice versa. In the arrangement shown in the Figure the primary control is effected by an azimuth gyroscope turning a baffle 11 between opposed jets 3, 6, and 4, 7 so as to vary the pressures transmitted through pipes 8, 9. These pressures act on a diaphragm 12 coupled on the one hand to a turn indicator 13 and on the other through an adjustable compound lever system 17, 19 with a swinging jet tube 18. The leverage ratio is varied by a movable link 20 pivoted at 23 to a rod actuated by a diaphragm subject to the varying pressure generated in a tube 28 by variations in the speed of translation. The jet tube which is normally centralized by a spring 31 controls the operation of a double acting piston coupled to the rudder 39. An arm 41 on the piston rod is coupled through a dashpot 45, lever 48 and blade spring 50 with the jet tube to give a follow-up effect. In a modification the link 14 couples the diaphragm 12 directly to an arm on the jet tube and the follow-up dashpot is operated by a diaphragm loaded by centralizing springs and subject to the pressures in the control conduits 34, 35. In the form shown in Fig. 3 a modified follow-up arrangement is used. A diaphragm 261 linked to the jet tube is subject to the air pressure produced by the movement of a sylphon bellows 255 operated by a piston subject to the pressures in the conduits leading to the rudder motor. After the elapse of a certain time a leakage aperture adjusted by a throttle 263 permits the pressure within the bellows to return to atmospheric pressure. In order to maintain a linear displacement curve a loading spring 272 having a non-linear characteristic is provided. Specification 468,487, [Group XXXV], is referred to. The Specification as open to inspection under Sect. 91 stated also that the controlling impulse may be derived from a compass or from an altimeter. This subject-matter does not appear in the Specification as accepted.

Abstract: 724,411. Fluid-pressure servomotor control systems. GENERAL MOTORS CORPORATION. Feb. 11, 1953 [Feb. 23, 1952], No. 3793/53. Class 135. The control valve in a liquidpressure - operated steering mechanism for motor vehicles which supplies and exhausts pressure liquid to and from a servomotor, comprises a hollow two-part valve spool 45, Fig. 3, having a central land 30 and larger diameter end lands 31 so. that when the spool is displaced from its neutral position in a easing 15 a selfcentring force is produced by the liquid pressure. The spool is mounted on a spindle 36 having an enlarged tubular end 360 housing seats 37 for the reception of the ball-end 110 of a pitman arm 11, Fig. 1, which is connected to the steering column, and resiliently maintained in neutral position by springs 43. The casing is secured to a cross-shaft 13 which through universal joints 20, rods 19 and joints 21 is connected to the road wheels. Ports 50, 51, 52 in the valve casing are connected to a supply pump, sump and the opposite ends of a doubleacting servomotor 230 respectively, the cylinder of which is connected to the shaft 13 and the piston through its rod 23 fixedly pivoted to the vehicle frame. In the neutral position of the spool 45, pressure liquid from the pump passes to both sides of the servomotor piston and from there to the sump. On movement of the valve spool, e.g. to the left from neutral position by movement of the arm 11, the land 30 cooperates with the casing 15 to close the lefthand port 55 to connect the associated end of the servomotor fully with sump whilst the righthand land 31 reduces the opening of an associated spill port 56 and more widely opens the right-hand pressure port 55. Thus pressure liquid is initially spilt through this spill port to sump and the initial application of power steering effort cushioned due to the larger area of the land 31. Increase of power steering effort up to the maximum effort may be applied gradually and proportionately to the applied manual effort, the driver experiencing " feel " due to the tendency at all times for the spool to move towards its neutral position.
